Using the linear combination method what is the solution to the system of linear equations 7x - 2y = -20 and 9x + 4y = -6
Ghella [55]

x should equal -2 and y should equal -3 to solve this i multiplied the first equation by 2 then got rid of the 4y and -4y then i added the 14x to the 9 equaling 23x and added the -40 to the -6 which became 23x=-46 i solved this getting -s for x, then i plugged that into the equations to get y which was -3
